Abstract
The methodological approach to identification of gasoline with an admixture of diesel fuel was presented. The approach involves using of gas chromatography–mass-spectrometry analysis of altered mixture. An algorithm of gas chromatography profile treatment includes analysis of extracted ion chromatogram for searching of polyaromatic hydrocarbons with 2 to 4 aromatic ring, mostly naphthalene, anthracene, phenanthrene and pyrene derivatives. The complex of specified components can be used as indicator of gasoline presence in mixture in the case if its chromatographic profile by total ion chromatogram is typical for diesel fuel. Obtained results show in common high similarity of chromatographic profile of altered diesel fuel and gasoline with small admixture (0.25 vol.%) of diesel fuel. A wrong identification results may be obtained without taking into account presence of pointed polyaromatic hydrocarbons. Such complex cannot be found entirely in pure diesel fuel in initial or altered state because its components are below or about of limit of detection. Determined limit of detection for polyaromatic hydrocarbons (naphthalene, phenanthrene, anthracene, pyrene) is 1.8-2.2 μg/ml.
